CAME MACHINE.

Original application filed November 10, 1924, Serial No. 748,878.

This invention relates to machines for producing a finish on. cames, and more particularly one of its particular applications is for the purpose of giving a particular char acter of leaf edge or surface to the general form of lead cames made in an H section. Among its objects are to economically produce a variegated or irregular edge on the leaves of the came and the surface, in a way that will preserve the essential structural characteristics of the came for its purpose of holding the glass, and ready use for assembly, but will give to the came the appearance which may be called an antique finish. Such particular objects involve the changing of a perfectly straight extruded, or the old fashioned. cast lead came, into a came with constantly irregular edges, or irregular widths of leaves, or irregular surface, or any of these irregularities for appearance, in combination, and to do so with economy and with a result that produces in the various lengths of came used in a leaded wlndow, irregularities throughout the lattice of the came. Another object is to produce such irregularities in a way that will insure the edges of opposed leaves being substantially in registration so that when glazed into the window the edges will approximately register and provide a clear edge vision without seeing the cemented underside of one leaf extending beyond the edge of the leaf on the other side of the glass.

WVhi'le such lead cames, sometimes called calms, are mostly used in short sections, the entire irregularity, to produce the effect and artistic finish, need extend usually over a short section of came, but should it be desired to make the irregularities vary over considerable length, modifications of the machine, as hereinafter described, also provide therefor to any length of came that might be used in. practically all. glazing work;

In the preferred form of such machines, I

tion, and variable members engage the edges of the leaves, providing enough resistance to pull the came through the machine and impress the irregularities upon the leaves limited to the edges and the outer surface. The centre rolls engaging the heart provide driving engagement to pull the came.

In the forms covered by this divisional application I prefer to have the means for driving the came blank include a driving engagement of the central rolls on the heart of the came, and to permit the edge of the leaves to be deformed irregularly by engaging surfaces capable of irregular displacement for upper and lower leaves, and to that may be added the provision of rollers to assure irregularity on the outer surfaces of the cames. The lead in such cames is very ductile and liable to misformation in the handling, so that difficulties arise in making specially formed leaves as to surfaces or edges that will still meet the requirements for artistic purposes, and will likewise provide a came meeting the structural requirements for use and ready assembling. This invention aims to provide such machine in simple form, adapted to the required variations for production, and for high speed of operation, as well as a machine that may be used in any shop to provide small quantities of cames having the particular characteristics of finish for a particular window, or for each particular set of windows that go into one structure.

This is particularly provided in the case of a machine that may be hand manipulated to produce artistic irregularities on the leaves but with power means to facilitate driving of the came through the mill, although with hand-driven mil] the irregularities may likewise be produced when very small quantities are desired or power is not conveniently applicable to the machine.

Various arrangements of mills may he used, with some of the parts herein shown and described, or other modifications with out using the particular entire combination, and for producing a great variety of finished product, without confining this inven tion to the specific embodiments herein de scribed.

Particular forms of these machines will now be described with reference to the drawit passesthrough the mill, showing a modification regarding the sin'face-forming of the leaves. v

The machine as shown in Figs. land 2, comprises a base with supports for the shafts 1. and 2, which respectively carry the mem bers and 1 having juxtaposed irregular facesadapted to engage the heart of the came on the bottom and top, so that by the driving through the pulley 19 of the gears and 41 force the 17 and 18, the members 3 came blank'between these members.

Loosely mounted on the shafts 1 and 2 are also the bosses 6 and 7, which respectlvely carry the cam surface members 8 and 9, subject to slight oscillation so that the two cam surfaces may be approached or spread away from each other more or less, but always in a position in the plane of the came leaves, there being-lone boss and cam in each case on either side and adjacent to the driving members 3 and 4 respectively. In the'case of cam 8, the arm is bifurcated so that it engages each of the two bosses 6, andby its bifurcation clears the driving member 4, while the spring 12 serves to normally hold the lever 10 and 1 thereby the cam 8 in its most retraetive poition away from the came. Similarly the arm 11 is offset and also bifurcated so as to 'engage'both parts 7, and thereby manipulate the cams 9-9, while it also is spreadby the spring 13 to normally keep the cams $1 9. at "their most retracted position, the arm 11 in any event being so offset as not to interfere with the passage of the finished came;

Both levers 10 and 11 are then connected by a-spring 14 so as to normally hold them in a balanced position against the pressure of springs 12 and 13, while the handles at the top provide for means to manually grip both handles and pull them together with one hand and vary thereby the positions of 1 the cams 88and 9-9., The cheeks 1515 and 16+16 prevent the bulging laterally of the leaves while being pressed into irregular edge shapes by the cams 89. But in the modifiedform' shown in 1 1g. 8 addi-' tional rollers 20 and 21 are provided for engagementwith the outer faces of the cams leaves, instead of the cheeks 15 and 16 'so that during the passage through the mill the outer surfaces will be supported and also given irregularity in accordance with the being shown in section on line engagement of the irregular surface of the roll 20 or the, roll 21. In this form the edge varying cams 8-8 and 99 are similarly provided for manipulation by hand and constant fluctuation as desiredQin order to produce the iregularities in the edges of the cames.

At all times one hand serves to rock both leversin either direction or to tighten them together, or let them spread apart, and thereby: produie' untold variations and con-- stant irregularities of the edges of the leaves and irreg gularities between theupper two edges and the lower two edges, but owingto the positive control of both can'is 88,.

the irregularities of both leave edges on that side of the heart will be uniform. and the same result is assured on the lower two edges on the other side; of the heart;

Thus a straight came blank A. with the straight heart B passes through the mill and emerges as an antique camewith the irregularities shown at A, and with certain ir-I regularities in the surface of the heart as shown at B, and if the irregular face'rolls 20 and 21 are used, then the surface as well as the edges of the cames have the complete antique finish by this simple hand-controlled V mechanism. 1 p

While a belt may drive pulley 19, any suitable power-drive may be used, and also hand-drive may be resorted'to provided that the driving'of one ofthe shafts correspond ingly drives the other in the same direction,

so that the heart-engaging members 3 and e'uniformly gripthe heart'and assure the proper driving of the blank through the mill to subject it to the manipulation which P.I?O-

vides the antique finish.

While various modifications may be made from the particular forms of embodiment of my invention herein shown and described, without departing from my invention, what I claim and desire to secure by Letters Patent is: 1' r r 1. A came mill having cooperating rolls to drive andreform a came blank, associated hand-manipulated means adapted to instant and irregular manipulation controlling leaf edge engaging members whereby constantly varying formation of the leaves can be made during the driving of" the came through the mill at the will of the operator. 1

2. A came mill having cooperating rolls to. drive a came blank, associated hand-manipulated means adapted to constant variation, leaf-engaging members subject to, said constant variation for greater or less impingement upon the leaves,vwhereby varying formations of the two-.leaves-on each side com .ared with the two leaves on the other si e of the came areelfected' at the will of the operator.

3. A came mill having power-driven means to force a'came blank throughleafmanipulating members, a pair of cams adapted to operate simultaneously and forced to varying pressure against the edge of the came leaves on one side of the heart, means for normally holding both said cams in the position of least pressure and handmanipulated means for giving a constant variation of the pressure or displacement at the will of the operator during the movement of the came blank through the mill.

4. A came mill having hand-manipulated means for causing constant irregularity of leaf finish to convert .a came blank into an antique finished blank, including means for driving the blank by engagement with the heart, means for causing irregular contraction of the leaf edges, and means to prevent lateral bulging of the leaf faces simultaneous with surface deformation thereof.

5. A came mill having hand-manipulated means for causing voluntary irregularities of leaf finish to convert a came blank lnto an antique finished blank, including means for driving the blank by engagement with the heart, means for causing irregular edges on the leaves and means to cause irregularities on the leaf surface simultaneously.

6. A came mill having cooperating rolls to drive and reform a came blank, manuallycontrolled means adapted to instant and irregular manipulation to vary the position of the leaf edge engaging members, for the purpose described.

In testimony whereof, I have signed my name to this application this 14th day of June, 1926.
